**NUCLEAR REGULATORY COMMISSION** 

**10 CFR Part 40**

**[NRC–2011–0072]**

**RIN 3150–AI95**

**Regulatory Changes To Implement the United States/Australian Agreement for**  **Peaceful Nuclear Cooperation; Corrections** 

**AGENCY :**  Nuclear Regulatory Commission.

**ACTION :**  Final rule; correcting amendments.

**SUMMARY :**  On November 8, 2011, the U.S. Nuclear Regulatory Commission (NRC or the Commission) published in the Federal Register a final rule (76 FR 69120) that amended the NRC’s regulations to implement the 2010 ‘‘Agreement between the Government of Australia and the Government of the United States of America Concerning Peaceful Uses of Nuclear Energy.’’ The present NRC action is necessary to relocate a new section added by the final rule, and to make a related conforming change to the final rule.

**DATES :**  This correction is effective December 20, 2011, and is applicable to November 8, 2011, the date the original rule became effective.

**FOR FURTHER INFORMATION CONTACT :**  Cindy Bladey, Chief, Rules, Announcements, and Directives Branch, Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555–0001, telephone: (301) 492– 3667; email: Cindy.Bladey@nrc.gov.

**SUPPLEMENTARY INFORMATION :**  This action corrects the final rule published on November 8, 2011 (76 FR 69120). Specifically, the new section in Title 10 of the Code of Federal Regulations (10 CFR) Part 40 is added as § 40.56 rather than § 40.52. This change is necessary because 10 CFR 40.52 through 40.55 were proposed to be added by a previous NRC rulemaking (75 FR 43425; July 26, 2010) that the NRC now intends to publish as a final rule. A conforming change is being made to the revised 10 CFR 40.13(c)(5)(v) provision, so that it will contain the proper cross-reference to § 40.56. These amendments are administrative in that they make no substantive changes to requirements, and the NRC accordingly finds that notice and opportunity for public comment on this corrective action is
unnecessary. List of Subjects in 10 CFR Part 40

Criminal penalties, Government contracts, Hazardous materials transportation, Nuclear materials, Reporting and recordkeeping requirements, Source material, Uranium.

For the reasons set out in the preamble and under the authority of the Atomic Energy Act of 1954, as amended; the Energy Reorganization Act of 1974, as amended; 5 U.S.C. 552 and 553; and the Energy Policy Act of 2005; Public Law 109–58, 119 Stat. 594 (2005); the NRC is adopting the following amendments to 10 CFR part 40.

**Airworthiness Directives; Rolls-Royce plc (RR) RB211–Trent 800 Series**  **Turbofan Engines**

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-Trent 800 Series Turbofan Engines. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fuel leaks from the engine due to damage to sections of the fan case low-pressure (LP) fuel tubes. We are issuing this AD to prevent engine fuel leaks, which could result in risk to the airplane.

**DATES :**  This AD becomes effective January 24, 2012. The Director of the Federal Register approved the


### 78806 Federal Register / Vol. 76, No. 244 / Tuesday, December 20, 2011 / Rules and Regulations

incorporation by reference of certain publications listed in this AD as of January 24, 2012.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on August 22, 2011 (76 FR 52288). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Fuel leaks from the engine have occurred in-service due to damage to sections of the fan case Low Pressure (LP) fuel tubes which run between the Low Pressure and the High Pressure (HP) fuel pumps. This damage has been caused by frettage between the securing clips and the tube outer surface, which has caused localised thinning of the tube wall thickness. The thinning of the tube wall causes the tube to fracture and fuel loss to

occur.

The corrective action includes inspection of the tubes and replacement of the associated clips. The fretting and thinning of the fuel tubes is caused by relative movement between the tubes and the clips. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Correct Title in Rolls-Royce Service Bulletin

A commenter, Air New Zealand, requested that we change the service bulletin reference from ‘‘RB.211–73– D685’’ to ‘‘RB.211–73–AD685.’’

We agree. The changed the AD to correct the service bulletin reference. Request To Change Service Bulletin Revision Number

Three commenters, American Airlines (American), Delta Airlines (Delta), and the Boeing Company (Boeing), suggested that we change compliance from Revision 5 to Revision 6 of the RollsRoyce Service Bulletin.

We agree. We changed the AD to use RR SB RB.211–73–AD685, Revision 6, dated February 21, 2011, which is the latest version of the service bulletin. Request To Allow Compliance to Earlier Revisions of the Service Bulletin

One commenter, Delta, asked that engines previously inspected per Revision 3 of SB RB.211–73–AD685, dated August 18, 2009; or Revision 4 of SB RB.211–73–AD685, dated January 20, 2010 or Revision 5 of SB RB.211– 73–AD685, dated August 18, 2010; to have met the initial inspection requirements of the AD.

We agree. We added a new paragraph to the AD called ‘‘Previous Inspection Credit’’ which provides credit for performing the initial inspection according to the requirements of Revisions 3, 4, or 5 of the SB. Request To Revise Cost of Compliance

A commenter, American Airlines, requested that the cost estimate per engine be increased to $905. American noted that the AD creates repetitive not one-time expenses due to the need for repetitive inspections. American also asserted that the estimate in the NPRM (76 FR 52288, August 22, 2011) of labor hours to comply with the AD was not accurate. American suggested 8 labor hours per inspection is a realistic figure.

We agree in part. While the AD does require repetitive inspections, we do not agree with including repetitive expenses for inspections in our cost estimate. We only include the cost of one inspection cycle, even if the AD requires repetitive inspections, in our cost estimates. We agree our labor estimate should be increased. We accept that 8 labor hours is a realistic estimate of labor hours and allows us to make a more accurate assessment of labor cost. We changed the estimate of work hours in the AD from 3 to 8. We also corrected the cost of the parts required from $225 in the NPRM to $884. We revised the total cost to comply with the AD from $52,800 to $172,040. Request To Revise Initial Inspection Paragraph

A commenter, Boeing, requested that the Initial Inspection paragraph be revised by including the following: ‘‘Inspect the Fuel Oil Heat Exchanged (FOHE) mounting hardware for signs of damage. Use paragraph 3.A.(4) of the Service Bulletin RB.211–73–AD685, Revision 6, dated February 21, 2011.’’ Boeing noted that damage or wear to FOHE mounts may contribute to low pressure (LP) fuel tube cracking. Delta Airlines commented further that EASA AD 2010–0188 requires this FOHE mount inspection because it requires accomplishment of the entire service bulletin when doing the inspection. For clarity, Delta requested that the final rule include a comment that the inspection requirements do not mandate the FOHE mount inspections.

We do not agree. The requirement of this AD to inspect the fuel tubes is sufficient to ensure safe operation. The repetitive inspection intervals for fuel tubes required by this AD consider observed FOHE mount wear. This AD does not require inspection of the FOHE mounts. We did not change the AD based on this comment. Request To Add Requirement To Remove Damaged Fuel Tubes

Two commenters, Boeing and Delta, requested clarification regarding when to replace fuel tubes. Boeing requested that under ‘‘Actions and Compliance’’ the following requirement be included: ‘‘Removal and replacement of damaged fuel tubes (P/N FK23986) in accordance with paragraph 3.A.(5) of the Service Bulletin RB.211–73–AD685, Revision 6, dated February 21, 2011.’’ Boeing indicated that rejected fuel tubes need to be replaced to avoid fuel leaks. Delta indicated that the On-wing Inspection and In-shop Inspection paragraphs do not include information about replacing tubes when needed as the result of inspections. Delta also noted that the Repetitive Inspection paragraph does discuss replacement of these parts when needed.

We agree in part. Although parts that fail inspection may not be returned to service, we agree that clarifying when fuel tubes are replaced would help. Werevised the On-wing Inspection and Inshop Inspection paragraphs to indicate that the tubes should be replaced if they fail inspection. Request To Clarify Initial Inspection Requirement

One commenter, Delta, noted that under the Initial Inspection paragraph, one of the options for complying with the AD is to do the initial inspection before 3,000 hours since last inspection. Delta requested that we clarify the meaning of ‘‘last inspection.’’

We agree. We added a definition paragraph to indicate that our reference to 3,000 hours since last inspection refers to the inspection of the fan case LP fuel tubes for frettage between the securing clips and the tube outer surface part numbers FK22617, FK19213, and FK23986.


### 78807 Federal Register / Vol. 76, No. 244 / Tuesday, December 20, 2011 / Rules and Regulations

Request To Clarify Handling of Clips for Fuel Tubes

One commenter, Delta, asked that the final rule clarify how to handle the clips that hold the fuel tubes in place. Delta noted that paragraphs 3.A.(2) and 3.A.(3) (on-wing) and 3.B.(2) and 3.B.(3) of RR SB RB.211–73–AD685, which are referenced in the NPRM (76 FR 52288), do not include inspection criteria for the clips. Delta requested that we either require inspection or replacement of the clips with a new or serviceable part per the note in Paragraph 3.A. of the RR SB RB.211–73–AD685, which says that ‘‘clips should be removed and replaced one at a time to prevent pre-loading of the clip position.’’

We agree. The fretting and thinning of the fuel tubes is caused by relative movement between the tubes and the clips. Worn or fretted clips cause increased relative movement between the tubes and the clips and thus more tube wear and fretting. Clip wear is not repairable and so the clips cannot be reused. We, therefore, revised the AD by changing the On-wing Inspection and In-shop Inspection paragraphs to indicate that the clips must be replaced during the initial inspection and during every repeat inspection. Request To Clarify Repeat Inspections Paragraph

One commenter, Delta, requested clarification of the Repeat Inspections paragraph. Delta noted that this paragraph might be misinterpreted to mean inspection and tube replacement should be accomplished per paragraphs 3.A.(2), 3.A.(3), 3.B.(2), and 3.B.(3) of RR SB RB.211–73–AD685. Since these paragraphs only apply to replacement of the tubes, Delta believes the language should be clarified.

We agree. We revised the Repeat Inspections paragraph to clarify thatparagraphs 3.A.(1) through 3.A.(3) (Onwing) or 3.B.(1) through 3.B.(3) (Inshop) of RR SB RB.211–78–AD685 apply to the inspection.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance

We estimate that this AD affects about 110 products of U.S. registry. We alsoestimate that it will take about 8 workhours per product to comply with this AD. The average labor rate is $85 per work-hour. Required parts cost about $884 per product. Based on these figures, we estimate the cost of the AD on U.S. operators to be $172,040. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this AD:

1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866;

2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (phone: (800) 647–5527) is provided in the **ADDRESSES** section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  We are superseding an existing airworthiness directive (AD) for certain TCM and R–RM series reciprocating engines. That AD currently requires replacement of certain magnetos if they fall within the specified serial number (S/N) range, inspection of the removed magneto to verify that the stop pin is still in place, and, if the stop pin is not in place, inspection of the engine gear train, crankcase, and accessory case. This new AD corrects the range of S/Ns affected, requires the same replacement and inspections, and adds R–RM C–125, C– 145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines to the applicability. This AD was prompted by our awareness of an error in the previous AD applicability in the range of magneto S/Ns affected and of the need to include certain engines made by R–RM, under license of TCM. We are issuing this AD to prevent engine failure and loss of control of the airplane due to migration of the magneto impulse coupling stop pin out of the magneto frame and into the gear train of the engine.

**DATES :**  This AD is effective January 24,
2012.
